Place a large non-stick skillet over medium-high heat and add the lean ground beef.

Cook the beef until fully browned and crumbled, approximately 7 to 9 minutes; drain any excess moisture.

Add the minced garlic, grated ginger, and toasted sesame oil to the skillet and sauté for 2 minutes until fragrant.

Whisk together the soy sauce, sweetener, and red pepper flakes in a small bowl, then pour over the beef mixture.

Simmer the beef in the sauce for 3 to 5 minutes until the liquid reduces and forms a glaze.

Divide the cooked rice and steamed broccoli into four equal serving bowls.

Top each bowl with the Korean beef mixture, garnish with sliced green onions and sesame seeds, and serve immediately.
